MMCONFIG - What does this initials stand for?

[William Muriithi]

Hello,

For a long time, I have always seen this error when Linux is booting but
never got around figuring what the heck it all meant. So today, I spent and
hour or so just trying to figure out what the heck this so common error
meant.

I can say I have a good idea now on what MMCONFIG has to do with - PCI
configuration space access. Wonder though any body know the politics behind
this problem. From Linux post at the bottom of this email, it looks like
there is a lot I am still missing. Understandably as I do not follow
hardware trends closely.

PCI: BIOS Bug: MCFG area is not E820-reserved
PCI: Not using MMCONFIG.
